Functions

func IP6ZoneToInt

func IP6ZoneToInt(zone string) int

IP6ZoneToInt converts an IP6 Zone net string to a syscall int returns 0 if zone is ""

func IP6ZoneToString

func IP6ZoneToString(zone int) string

IP6ZoneToString converts an IP6 Zone syscall int to a net string returns "" if zone is 0

func IPAF

func IPAF(ip net.IP) int

IPAF returns the syscall AF_* type for a given IP address returns AF_UNSPEC if unknown

func IPAddrToSockaddr

func IPAddrToSockaddr(addr *net.IPAddr) syscall.Sockaddr

IPAddrToSockaddr converts a net.IPAddr to a syscall.Sockaddr. Returns nil if conversion fails.

func IPAndZoneToSockaddr

func IPAndZoneToSockaddr(ip net.IP, zone string) syscall.Sockaddr

IPAndZoneToSockaddr converts a net.IP (with optional IPv6 Zone) to a syscall.Sockaddr Returns nil if conversion fails.

func NetAddrAF

func NetAddrAF(addr net.Addr) int

NetAddrAF returns the syscall AF_* type for a given net.Addr returns AF_UNSPEC if unknown

func NetAddrIPPROTO

func NetAddrIPPROTO(addr net.Addr) int

NetAddrIPPROTO returns the syscall IPPROTO_* type for a given net.Addr returns -1 if protocol unknown

func NetAddrSOCK

func NetAddrSOCK(addr net.Addr) int

NetAddrSOCK returns the syscall SOCK_* type for a given net.Addr returns 0 if type unknown
